Sparkling wine bottle neck closure, has O-shaped seal ring stretching outward by rotating clamping bolt train nut along clockwise direction on clamping bolt such that seal ring seals bottle in bottle neck

摘要

The closure has an O-shaped seal ring (3) stretching outward by rotating a clamping bolt train nut (4) along clockwise direction on a clamping bolt (2) such that the seal ring seals a bottle in a bottle neck. A guide cap (1) prevents turning of the clamping bolt at an outer hexagon part, where a continuous cylindrical mold does not show the closure after assembly of the guide cap, the clamping bolt, the seal ring, the clamping bolt train nut and a final screw (5). The closure signals a user when the bottle is perfectly closed.
